All inlets equipped with Constant Airflow Regulators (CARs) to insure a constant rate of CFM regardless of static pressure in duct.

MPVS Series multi-port ventilators are highly versatile continuous duty rated fan units for residential and light commercial applications, and meet ENERGY STAR efficiency criteria for low energy consumption. The most popular use is central continuous exhaust ventilation of bathrooms, kitchens, laundry rooms, and other rooms where humidity is a controlling factor, since the fan has a single exhaust discharge duct directly to the outdoors.

The principle advantage of the MPVS central exhaust system is the assurance of controlled indoor air quality ventilation and the elimination of standard noisy bath fans, with the obvious benefi ts of reduced penetrations to the exterior of the building.

With the increased tightness of construction for energy effi cient buildings, there is a growing need of mechanical ventilation for indoor air quality. These fans are designed to serve this purpose as well, by providing effective bathroom ventilation, with the ability to run intermittently or continuously as needed. The quiet, energy effi cient permanent split capacitor external rotor motor has permanently sealed bearings that provide many years of maintenance free performance.
